I am a Ph.D. student in Prof. Jiawei Han’s Data Mining Group (DMG) at University of Illinois Urbana-Champaign (UIUC). I obtained my M.S. degree and B.S. degree also at UIUC, in Computer Science and Computer Engineering respectively.
I am especially passionate about developing self-supervised, unsupervised and weakly-supervised (i.e., leveraging minimal human supervision) text mining techniques for organizing and exploring text data. As such, I work at the intersection of data mining, natural language processing and applied machine learning. In the past, I have worked on text representation learning (ICLR’22, NeurIPS’21, NeurIPS’19), few-shot and zero-shot learning (ICML’23, NeurIPS’22), topic discovery (WWW’22, KDD’20, WWW’20), weakly-supervised text classification (EMNLP’20, AAAI’19, CIKM’18) and distantly-supervised named entity recognition (EMNLP’21). In the long run, my research is dedicated to mining structured knowledge from large-scale text data in label-efficient ways.
I am grateful for being supported by the Google PhD fellowship since 2021.
